Pearn P. Niiler

Pearn P. Niiler is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pearn P. Niiler rather than just read about it. In short: Pearn "Peter" Niiler (1937, Tartu, Estonia, – 15 October 2010, San Diego) was an American oceanographer known for his scientific contributions to ocean circulation and the Global Drifter Program. Early life and education In 1948, Niiler, his six siblings and parents arrived in Pittsburgh from a displaced persons camp in Germany where they had lived after fleeing Estonia during World War II.

Key takeaways

  • Pearn P. Niiler belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pearn P. Niiler to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pearn P. Niiler from memory before moving on to harder problems.

Reference excerpt

Pearn "Peter" Niiler (1937, Tartu, Estonia, – 15 October 2010, San Diego) was an American oceanographer known for his scientific contributions to ocean circulation and the Global Drifter Program.

Early life and education In 1948, Niiler, his six siblings and parents arrived in Pittsburgh from a displaced persons camp in Germany where they had lived after fleeing Estonia during World War II. His father, Herbert Niiler, coached the Estonia national basketball team at the 1936 Olympic Games and later ran a YMCA camp near Zelienople, Pennsylvania. Peter Niiler studied engineering at Lehigh University and graduated in 1960. In 1964, he received a doctorate from Brown University where he studied applied mathematics and fluid mechanics.

Scientific career A Woodrow Wilson scholar and a Fulbright fellow he studied at Cambridge University, UK and was a postdoctoral fellow at Harvard. In 1966, he joined Nova University where he studied the Florida Current and the Gulf Stream. He became professor of oceanography at Oregon State University in 1974. He became professor at the Scripps Institution of Oceanography in 1982, where he worked in the Physical Oceanography Research Division. He was a Scripps Distinguished Professor.

Niiler designed ocean drifters for measuring direct circulation flow and other instruments for ocean observations. He was the scientific father of the Global Drifter Program and one of the persons responsible for organizing a Boulder, Colorado, meeting in 1982 which initiated the program itself. One of his more clever designs was an ocean drifting measurement device he called the holey sock. Beginning in 2002, Niiler became involved in tropical hurricane research and his group deployed the first groups of thermistor chain drifters before approaching hurricanes. His final field project was related to tropical hurricanes influence on ocean mixing in the Western Pacific. The project was ongoing when he died, and he coordinated deployment of the thermistor chain drifters of his design during that project. His thermistor chain drifters sampled Typhoon Fanapi in September 2010. Niiler was particularly interested in typhoon cold wake to study relaxation of the mixed layer temperature after cyclone passage. His interests included measurements of flow and theory of variability of eastern boundary current systems, relationship of heat flux to global sea surface temperature variability, Lagrangian circulation measurements in mixed layers of the world ocean, and response of upper ocean to tropical storms. He was named fellow of the American Geophysical Union in 1986. He was an ongoing distinguished visiting scientist at the Jet Propulsion Laboratory for 31 years beginning in 1979.

Personal life He was married to Ann Easton in 1960 and had two sons, Eric and Benjamin. They divorced in 1974. His second marriage was to Nancy McCaleb. Their daughter is Ashley. According to Scripps News "He had a passion for architecture and designed numerous homes and several buildings. He played a leading role in creating the distinctive design of the W.M. Keck Foundation Center for Ocean Atmosphere Research, in which his office was housed. He was a painter, a gourmet chef, and an aficionado of wine and travel." He was also supporter of the dance company founded by his wife, Nancy McCaleb.

Worked examples

Example 1 — a first encounter with Pearn P. Niiler

Start with the simplest possible case. Write down what Pearn P. Niiler claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pearn P. Niiler before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pearn P. Niiler ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pearn P. Niiler

In research
Pearn P. Niiler appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pearn P. Niiler in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pearn P. Niiler is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1937 births, 2010 deaths, American oceanographers, so understanding it makes those chapters shorter.
In everyday life
Look for Pearn P. Niiler outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
